...trudged forward and stumbled onto this path of brick and ivy and erudition, which looked so similar to the other roads before me—but, thankfully, led me clear of New Haven...
...path continues to fork and also to twist and climb...
...flight simulator for pilot training that would show on a screen the same unfolding landscape the pilot would see from the air. To do this, the Utah scientists first had to program into the computer a precise mathematical model of every tree, house and mountain in the flight path. Then they instructed the machine to put each of those objects into three-dimensional perspective, to give it the illusion of depth and to eliminate those surfaces that would be hidden from the viewer's line of sight...
Today's most advanced graphics systems take Evans and Sutherland's procedure one step further. Using a programming technique known as ray tracing, they follow the path of each ray of light as it travels from its source, say the sun, to the viewer's eye. Upon striking a surface, each ray will be absorbed, reflected or transmitted in accordance with the laws of optics. Programmed with a mathematical model of the behavior of light rays, the machines can re-create lighting effects of dizzying complexity. Caltech's Jim Kajiya, for example, has used ray tracing to show how ripples...
...real the intellectual Harvard bubble may seem, we live in a city where crime is an unfortunate reality. Despite the extra layer of security that blue light phones provide for those walking back to the Quad at night, students must take other precautions, including staying on the designated safe path, utilizing Harvard University Campus Escort Program, or merely walking in a group. Ultimately, one cannot rely on others for security—one must protect oneself...
